R
esearchers from the University of
Warsaw, Google AI and deepsense.ai take
on a new reinforcement learning challenge
on Cloud TPU hardware accelerators. The
goal of the experiment is to end-to-end train
an artificial intelligence to play video games
fully inside a computation graph.
A team from the University of Warsaw, made
up of Piotr Miłoś, Błażej Osiński and Henryk
Michalewski, has started a collaboration on
reinforcement learning research with Łukasz
Kaiser from the Google Brain team and with
researchers from deepsense.ai. This project
is connected to a research programme on RL
that deepsense.ai started last year.

In the experiment, an artificial intelligence
will be end-to-end trained to play video
games fully inside a computation graph.
Assuming that a game simulator would also
be a part of the graph, this could make tasks
such as training AI to play video games
even faster than what deepsense.ai’s team
achieved last year. The intent is to run the
training process entirely on Cloud TPUs,
which are new machine learning accelerators
designed by Google. This will save time
previously spent on communication between
accelerators and a host computer.
The main experiments are being run on
Cloud TPUs via the TensorFlow Research
Cloud programme and supported by Google
Warsaw’s Antonio Gulli, Ignacy Kowalczyk
and Maciej Pytel, who are helping to deploy
experiments on the Google Cloud Platform.
TFRC provides ML researchers with access
to second-generation Cloud TPUs, each of
which provides 180 teraflops of machine
learning acceleration.

N
okia, together with its partners
Herkules, Pozbud and Wasko, and
Poland’s state-owned railway operator
PKP Polskie Linie Kolejowe SA (PKP
PLK) have signed a five-year contract
to deploy a nationwide turnkey GSM-R
and mission-critical backhaul network to
enhance railway security and reliability
throughout the country. This project,
Nokia’s largest-ever GSM-R contract, will
provide PKP/PLK with one of the biggest
state-of-the-art railway communications
networks in Europe.
The new network will enable the PLK
railway company to fulfil European Union
requirements for ERTMS (European
Rail Traffic Management System), the
bloc’s European-wide standard for
railway signalling. The project is majority
funded by the EU and complemented
by Polish State funds. GSM-R is a
mandatory part of the ERTMS, which
is under deployment across Europe
to help rail operators like PKP PLK
seamlessly manage and control trains
in combination with the European Train
Control System. The solution delivered
by Nokia will help PKP PLK increase train
traffic reliability and safety, ultimately
improving passenger satisfaction.
Nokia will provide installation,
commissioning, third-party integration,
first-line care and maintenance for
13,800 km of the GSM-R network, plus
more than 11,000 km of optical fibre-
based backhaul network infrastructure
with IP Multiprotocol Label Switching (IP/
MPLS) and dense wavelength division
multiplexing (DWDM) optical network
equipment. It includes an end-to-end
GSM-R solution (radio and core network
including NetAct, Messaging and diverse
third-party products), an IP-MPLS core
network, security and DWDM technology
for the fibre-optic network. Herkules,
Pozbud and Wasko will be responsible for
civil works, including construction work for
laying fibre.
